The bill, proposed by President Barack Obama, would have supported 22,000 jobs in Massachusetts and cut taxes for small businesses and families, Democrats said. The AJA would also have invested $50 billion in infrastructure repairs, $850 million of which would have gone to Massachusetts.

"Jobs are the major issue in this campaign," said McGovern. "Actions speak louder than words."

Warren has been a big supporter of the President's efforts to jumpstart the economy through the use of jobs bills, arguing that there is plenty of work that needs to be done and plenty of people ready and willing to do it.

"While families across this state were struggling to make ends meet, Scott Brown voted against President Obama’s jobs bill because it would have been paid for by asking millionaires and billionaires to pay their fair share," Warren said.

"I think that’s wrong. I don't want to go to Washington to fight for billionaires and big corporations. I want to go to Washington to fight for working families and small businesses.”

"We need Elizabeth Warren badly," said Palmieri to the crowd gathered at the campaign's headquarters on Park Avenue in Worcester.

The Councilor said that Warren understands the importance of investment in fundamental infrastructure throughout the Commonwealth and that such investment is essential to the growth of the City of Worcester.

Lt. Gov. Murray said the Bay State has made enormous economic strides through cuts and consolidations as well as through generating additional revenue, noting that Massachusetts is performing better than most other states in terms of unemployment and economic recovery.

"Elizabeth Warren is offering solutions," he said. "It's the public and private sector working together."

Brown has defended his votes against the AJA and two other jobs bills based on the affect they would have on other Americans through increased taxes.

"You have to read the bill, you have to see how it affects everybody else," Brown said in Wednesday night's Senate debate, adding that he did go on to support a bipartisan jobs bill.

That bill came from Democratic Senate Majority Leader Harry Reid, who was glad to receive Brown's crucial vote from across the aisle. Brown also introduced bipartisan legislation for hiring heroes and withholding tax relief similar to pieces of Obama's own jobs bills that came after.

Meanwhile, Brown campaign manager Jim Barnett issued a statement on Thursday after reports surfaced of union members saying they were forced to hold Warren signs outside the Senate debate in Springfield or face financial repercussions.

"It is shameful and wrong for union leadership to threaten workers with expensive fines unless they attend events for Elizabeth Warren," Barnett said.

"Elizabeth Warren should immediately condemn these tactics and apologize to union members who have been compelled by their leadership to support her against their will."
